PRES SU RE-REGULATO R FO R SODA-WATER SPECIFICATION forming part ofLetters Patent No. 255,467, dated March 28, 1882.

Application filed November 5, 1880. Renewed February 9, 1882. (Nomodel.)

To all whom it may concern:

Be it known that 1, GEORGE S. SLOCUM, a citizen of the United States,residing at Newport, in the county of Newport and State 'of 5 RhodeIsland, have invented certain new and useful Improvements inPressure-Regulators for Soda-Water Generators and I do hereby declarethe following to be a full, clear, and exact description of theinvention, such as will enable others skilled in the art to which itappertains to make and use the same, reference J being had to theaccompanyingdrawiugs, and to letters or figures of reference markedthereon, which form a part of this specification.

The object of this invention is to provide means whereby the pressure ofgas in a soda water fountain will automatically regulate itself byallowing a valve to open for the influx of more gas whenever saidpressure falls below the proper degree. This object I attain by theconstruction and combination of devices hereinafter particularly setforth.

The drawings accompanying this specification represent, in Figure 1, ageneral view of a bottling-machine and generator with my improvedregulator, and in Fig. 2 a sectional elevation of the regulator.

A represents a generator for producing carbonic-acid gas, such as isused by manufacturers of soda and other aerated waters, theoutlet-coupling which connects this generator with the fountain beingshown at a.

Bin the drawings represents the fountain, so called, being the closedvessel in which the water aerated by the gas from the generator A isheld and supplied to the bottles.

in the drawings represents a pressureregulator valve to automaticallygovern the supply and pressure between the generator and fountain. Asvarious valves may be employed in this connection, and in carrying outthis principle of my invention, I do not restrict myself to theemployment of any special form of valve. The one I have herein shown issubstantially after the form of a pressure-regulator now in general use,in which the valvestem is supported upon an elastic diaphragm and theValve so constructed that when the pressure of steam in the service-pipefalls be- 50 low the adjusted point the valve opens to admit more steamto such point, and vice versa. As shown in the drawings, this valve isconstructed as follows: The valve per se is an on dinary conicalpuppet-valve, and is shown at b as secured to the upper end of avertical rod, c, the lower end of which rests upon an elastic diaphragm,d, secured at its margin within a hollow base, 0, having at its lowerpart an eduction-port, f, provided with a female screw for attachment tothe bottling fountain or receiver, the valve rod or stem being slottedvertically,

as shown at g, to receive a lever, h, and con stitute the fulcrum ofsuch lever, the base of this lever being pivoted to a post, 2', erectedupon the base e, while the free end of the le- 6 ver is weightedaccording to the pressure to be maintained in the fountain.

A compound lever may, if desired, be obtained by adding a secondweighted lever, j, disposed over the first, and pivoted at its bore to apost erected upon the opposite side of the base 0 and bearing upon thefirst lever.

The valve-seat is shown at k as formed in the under side of .a shelf, l,secured within the upper part of achambered or tubular head, m, 7disposed above the lever before named, and erected upon the base 6 byseveral upright columns, a n, &c., this valve-seat being annular andcommunicating with a vertical orifice, 0, created in the shelf 1. Abovethe shelf lthe 8o tubular head has a'female screw to adapt it to becoupled to the generator, in which the water is charged with gas.

Communication is bad between the generator and fountain by a passage,19, leading from 8 5 the valve-chamber q in the lower part of the head mdownward through one of the columns a, thence through the material ofthe base 0, and into the chamber of the latter below the a diaphragm,and the gas consequently escapes go from such chamber by theeduction-port f to the fountain.

Should the pressure in the fountain fall below the intended pressure, asdetermined by the weighted lever, the valve will open and an 9 5additional amount of gas under the head from the generator will flowinto the fountain until its maximum pressure is restored, when the valvecloses and communication between the generatorand fountain is cut off.Bythis means r00 the pressurein the fountain is maintained uniform.Hence the bottles are charged with a uniform pressure, and in additionthe time of the attendant is not occupied in constantly opening andclosing the cock between the two "es point. sels, as is now necessary.In testimony whereof I aflix my signature Having thus described myinvention, what I l in presence of two witnesses. claim as new, anddesire to secure by Letters GEORGE S. SLOOUM. Patent, is

In combination with the generator, fountain, and connecting-pipe of anaerated-water apparatus, a valve arranged in said pipe and operated bythe pressure in said fountain to open and admit afresh supply of gaswhen the pressure in said fountain falls below the proper 15 Witnesses:
